Description
Technical field
The utility model relates to a kind of heat injection and machine is adopted integrated apparatus.
Background technology
The thermal recovery technology is the effective means of viscous crude field exploitation.Oil-field thick-oil thermal recovery technology has been brought into play huge advantage at heavy crude heat extraction, has obtained insider's approval.Steam soak is a method the most frequently used in the heavy crude heat extraction.The steam soak process generally is divided into three phases: the phase I is to annotate the vapour stage.This stage is injected oil reservoir fast with high-temperature steam.Second stage is the stewing well stage.Closing well immediately after annotating vapour and finishing is convenient to heat effectively exchange in oil reservoir that steam carries, thus the heating oil reservoir.Phase III is the oil recovery stage, and this stage generally comprises blowing and two stages of oil pumping again.Pressure is higher near the shaft bottom when annotating vapour because of HTHP, and for blowing provides energy, flowing phase was generally kept several days to tens of days, and this moment, main output object was condensed water around the oil well and the crude oil that heated in a large number.When bottom pressure and strata pressure near the time, just must change the oil pumping stage over to.The oil pumping stage need trip out steam injection tubing string lower sucker rod post, utilizes sucker rod pumping then.Recover the oil and finish, trip out rod string, steam injection again repeats.What the hoisting system that land oil thermal recovery operation notes are adopted adopted is rod pumping pump.The surface driving equipment of sucker rod pump is huge, such as beam pumping unit.Offshore oil production is subjected to the restriction of platform space, can not put so huge surface driving equipment, therefore can not use sucker rod pump to carry out lifting and recover the oil.
But in thermal recovery huff and puff oil recovery process, oil thermal recovery transfers the oil recovery stage to after annotating vapour, must trip out steam injection string, descends flow string then.In the process of changing tubing string, a large amount of flushing fluids, well killing fluid cause cold damage to the stratum, and thermal loss in a large amount of wells is arranged.Play lower tubular column continually.Play lower tubular column and can cause a large amount of heat-energy losses, heat waste is bigger under the situation that especially fluid temperature (F.T.) of Zhu Ruing is lower, calorific value is less, influences the thermal recovery effect.And, under the situation of changing tubing string repeatedly, improved cost, reduced operating efficiency.
